I'm not sure the reason then, but they're definitely right; it works fine with zsh, doesn't work with bash. I wrote a test script to try it myself.
I don't have fish installed and can't be bothered to go that far, but I suspect they're right about that as well.
- anotherhue 11mo agoenv bash is all well and good for normies, but if you're already on NixOS did you know you can have nix-shell be your interpreter and back flip into any reproducible interpreted environment you like? https://nixos.wiki/wiki/Nix-shell_shebang https://nixos.wiki/wiki/Nix-shell_shebang

- opello 11mo agoIt is strange, cursory digging for an explanation was a little more complex than I bargained for... https://github.com/torvalds/linux/blob/v6.17/fs/binfmt_script.c#L121-L134 https://github.com/torvalds/linux/blob/v6.17/fs/binfmt_scrip... I think it makes it to calling open_exec but there's a test for BINPRM_FLAGS_PATH_INACCESSIBLE, which doesn't seem relevant since 'bash' isn't like '/dev/fd/<fd>/..', but does provoke an ENOENT. https://github.com/torvalds/linux/blob/v6.17/fs/exec.c#L1445 https://github.com/torvalds/linux/blob/v6.17/fs/exec.c#L1445 Maybe someone else can explain it, I'd enjoy the details, and ran out of steam.
